Does anyone know of a house-plant watering system that
uses a moisture sensor to water plants via an electronic valve?

Every plant has different moisture needs... to sense moisture I just
poke my finger in, always works for me... and why not a simple
watering can?

The idea is to automate the process to save time. Since apparently no
one's ever thought of doing this, there's also a certain element of
novelty.

I use a reservoir (water dish below the plant ), the plant supported above
the reservoir and a acrylic yarn wick from the reservoir into the bottom of
the plant to draw the water up into the plant as needed. There are several
sites on the web which discuss this (Google wick watering). Again the key
is acrylic yarn for the wick and soaking the wick before inserting into the
bottom of the plant. I use a reservoir big enough so that is holds several
weeks of water so I can go on vacation with out worrying about the plants.
